FIG. 1.

(Color online) Schematic diagrams of (a) a suspended source/drain (SSD) OTFT and (b) a bottom-contact OTFT. From the cross-sectional view, the SSD OTFT shows a top-contact-like S/D structure rather than a bottom-contact S/D structure.

(Color online) (a) Optical image of SSD OTFT before printing the organic semiconductor (the image was taken from the back side of the substrate). The channel width and length of the transistor were 125 and , respectively. (b) Scanning electron microscope (SEM) image of SSD OTFT after printing TIPS pentacene. (c) SEM image of SSD OTFT in the channel region showing TIPS pentacene grains. (d) SEM image of TIPS pentacene on S/D electrode. The size of the TIPS pentacene grains ranges from .

FIG. 3.

(Color online) Transfer curves of ink-jet printed TIPS pentacene OTFTs (a) with conventional BC S/D structure and (b) with SSD structure. The field-effect mobility, threshold voltage, and subthreshold slope of BC OTFT were , , and , respectively. The SSD OTFT exhibited field-effect mobility, threshold voltage, and subthreshold slope of , , and , respectively. The channel length and width of both BC and SSD OTFTs were 125 and , respectively.
